N 0. 823,292. Specification of Letters Patent.

Application filed July 12 1905. Serial No. 269,295.

Patented June 12, 1906.

To all whom, it may concern.-

Be it known that I, EDWIN W. ROBINSON, a citizen of the United States, and a resident of Punxsutawney, in the county of J eiferson and State of Pennsylvania, have invented a new and Improved Rail-Bond, of which the following is a full, clear, and exact description.

nection between the nuts and the webs B and B of the adjacent rails. It is understood that by screwing up the nuts 0 and O the conductor A is t own very firmly against one side of the webs B and B, and at the same time the frusto-conical nuts C and C are drawn in firm contact with the walls of the apertures B and B to insure an exceedingly good electrical connection between adjacent rails.

The rail-bond described, the drawings, and readily structed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination with the rails, of a railond, comprising a conductor having a straight portion lying against the web of the rail upon one side thereof, and having angular screw-threaded ends projecting through apertures in the said webs, and frusto-conical nuts on the opposite side of the web from the conductors and engaging the screw-threaded ends, the ends of the nuts extending into the and illustrated in is very simpl The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claim.

practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in Which similar characters of reference indicate corresponding parts in both views.

igure 1 is a sectional plan view of the improvement and Fig. 2 is a perspective view of one of the frusto-conical nuts.

The conductor A, in the form of a metallic rod, abuts against one side of the webs B B of adjacent rails, and the said conductor is provided with angular screw-threaded ends A A rojecting through a ertures B and B formed in the webs B an B, respectively. On the threaded ends A and 2 are screwed nuts 0 and C from the side of the webs o 0- site to the one engaged by the conductor A, and the said nuts 0 and O are provided with frusto-conical ends C and 0 adapted to contact at their sides with the walls of the apertures B and B to insure a firm electrical con- EDWIN W.
